Introduction

Thank you for deciding for the blood pressure monitor SC 7600 from SCALA. Electronic

GmbH. To be able to utilise all advantages of the blood pressure monitor to the fullest, you

should carefully read these instructions before using the monitor. Keep the instruction

leaflet in a safe place.

Features of the SC 7600

The SC 7600 is a fully automatic digital blood pressure monitor for blood pressure

measurement on the upper arm. The measuring algorithm is state-of-the-art.

- The blood pressure monitor has fuzzy logic to identify the pumping pressure. If

the pumping pressure set in the factory (approx. 190 mmHg) is not sufficient, the

instrument identifies this and continues pumping.

- The instrument has 2 selectable memories each with 50 memory locations.

- The date and time are displayed and stored together with every blood pressure value.

- Additional WHO-Interpretation of blood pressure readings with coloured LED band (red:

hypertension; yellow: high normal; green: normal blood pressure)

- If your heartbeat is not regular, an icon (see page 9) appears in the LCD.

- If the battery icon is displayed, the batteries are discharged and the device cannot be

used until new batteries are inserted.

- The cuff is suitable for upper arms with a circumference between 22 and 32 cm.

Safety instructions

The blood pressure monitor SC 7600 enables you to monitor your blood pressure regularly.

However, you should never change the treatment which your doctor has prescribed. Self-

3

measurement means monitoring, it does not imply diagnosis or treatment.

Discuss unusual values with your doctor. Do not change the medication prescribed by

your doctor. The heart rate is not a useful indicator of the frequency of a cardiac pace

maker. Patients with cardiac arrhythmia should use the blood pressure monitor only after

consulting a doctor.

Instructions for measuring the blood pressure

In order to obtain comparable values, always measure the blood pressure under the same

conditions, i.e. in a relaxed atmosphere, not after the consumption of alcohol, not during a

meal and not after being exposed to physical or nervous stress.

If possible, make the measurement while being seated at a table.

How to put the SC 7600 into operation / changing the batteries

Put the supplied batteries in the compartment as

indicated on the back of the instrument. Use only alkali

batteries (LR6). Most low-price zinc-carbon batteries

(R6) cannot be used for more than 20 or 30

measurements. If the batteries are flat, an empty

battery will be displayed at the LC display above left:

(see Fig. 3). The battery needs urgent

replacement because you cannot use the monitor with

depleted batteries.

Caution: Do not dispose of depleted batteries with

the household waste. Also see disposal note.

Fig. 4

Alternatively to battery operation, the SC 7600 may also be operated with a special power

supply unit, which is also available from Customer Services. Use of a power supply unit not

approved by the manufacturer will destroy the blood pressure monitor

Troubleshooting and remedies

Possible errors which can occur during a measurement are listed in the table below.

Message Error description Correction

Pressure is not build up in the

cuff. Cuff not applied tightly

enough or leaky.

Apply cuff again and measure again.

Consult customer service if necessary

Pressure is built up very quickly

at the sensor. The cuff is too

tight or the bubble sticks.

Apply cuff again and measure again.

Consult customer service if necessary

Pump defective or pumping

error

Contact customer service

The pressure can not be

measured due to signal noise.

Please take the measurement on the left

upper arm. Make sure of the correct seat

of the cuff. Repeat measurement.

The pumping pressure is higher

than 300mmHg.

Contact customer service

or no display

Low batteries.

Please check and replace the batteries if

necessary. Do not use Ni-Cd or NiMH

rechargeable batteries

From many years of experience we know that most faults are the consequence of wrong

use. The most frequent causes of faults are excessive movement during the measurement,

11

The memory function

The SC 7600 saves up to 50 measurements in every memory area. Together with each

measurement (systolic, diastolic and heart rate), the date and time are also saved. The

measurement with the longest residence time in the memory is assigned number 1. All other

measurements increment by one until number 50. Then the memory is full. The next

measurement occupies memory location 50. The measurement formerly at location 50

changes to location 49 (etc., 4847 .... 21). The oldest measurement formerly at location

1 is lost.

Delete a blood pressure value from the memory

Press the MEMORY key to view the blood pressure value you want to delete. Pressing the

POWRER key instantly (and holding it for at least 4 secs.) displays dEL (for "delete") and

the number of the memory location.

Press the POWRER key instantly and the value will be deleted.

Delete all blood pressure values in the memory

Remove the batteries for about 5 minutes to delete all memory entries, the time and date

settings.

Or: Press the MEMORY key to display any blood pressure value. Pressing the POWRER

key instantly (and holding it for at least 4 secs.) displays dEL (for "delete") and the

number of the memory location Press the MEMORY key instantly and the LCD displays

dEL (for "delete") and ALL (for all memory locations).

Press the POWER key instantly and all values will be deleted. Time and date are not

deleted.

10

Setting the clock

After you have inserted the two batteries, you should set the clock. It starts with year

“2009”, „1/ 1“ (for the 1st month / 1st day) and “12:00“ o’clock after every battery change.

To set the clock, hold the MEMORY button (see Fig. 2) pressed for about 5 seconds. The

year 2009 blinks in the top left corner of the display.

Set the year with the ON/OFF (see Fig.1) button.

When the correct year is set, press the MEMORY button again. Now the 1 blinks in the top

left corner of the LCD. It stands for the month.

Set the month with the ON/OFF button.

Another press of the MEMORY button sets another 1 blinking. It stands for the first day in

the month.

Set the day with the ON/OFF button.

Another press of the MEMORY button takes you to the clock setting – the hours blink. As

earlier, set the clock with the ON/OFF button.

Pressing the MEMORY button advances to the minutes setting.

Set the minutes with the ON/OFF button.

A final press of the MEMORY button completes the setting of the date and time

7

The blood pressure measurement

Now connect

the cuff with the instrument by plugging the air

plug at the tube of the cuff into the socket on

the back side of the instrument (see Figs. 1

and 2). Put the cuff around your left upper

arm in such a way that the tube is directed

towards the bend of the elbow, with the lower

cuff edge ending about 2-3 cm above the

bend of the elbow.

Fig. 5

The cuff should be reasonably tight.

Before switching on the instrument, select “your” memory area with the select button, which

you want to use and in which you want to store your blood pressure values by pressing the

MEMORY button. (The BP monitor has 2 different memory areas each with 50 memory

locations. The other memory area can be used by family member or other person.)

After you press the button for selecting the memory area, the word USER 1 is displayed.

Another press of the select button displays the word USER 2.

So select ”your” USER memory. Then wait for 5 seconds until the display disappears. The

monitor has adopted your data and is now ready for taking measurements. Pressing the

ON/OFF button starts the automatic measurement. The cuff inflates to approx. 190 mmHg

pressure.

8

The automatic deflation starts the measurement. After about 3 seconds, a heart icon starts

blinking in the LC display. If a Korotkoff’s sound is detected already at that time, it means a

systolic pressure of more than 150 mmHg. Then the monitor re-inflates (to about 220

mmHg).

At the end of the measurement, the result is displayed in the LCD and the cuff deflates and

the measuring value is entered in the selected memory area.

Irregular heartbeat

If your heartbeat is not regular (irregular), the intervals between pulses are different. If this

happens while you are taking a measurement, the icon ” ” appears in the LC display.

Reasons for irregular heartbeat: (not complete)

Not a cause for concern:

- Sport activity, sauna, stress.

- Measuring error such as loose cuff, wrong posture during measurement

Cause for concern: (not complete)

- Cardiac arrhythmia

If irregular heartbeat is displayed regularly, consult your doctor.

Aborting a measurement

You can stop the measurement at any time by pressing the ON/OFF button. The BP

monitor deflates the cuff instantly.
